CASH-REGISTER.

SPKCJFICATIQII forming part of Letters Patent No. 309,240, dated December 16, 188:.

No model.)

To all whom it may c07wcrn:

Be it known that I, THOMAS llIUNNELL, of Mount Sterling, in the county of Montgomery and State of Kentucky, have invented certain new and usefulImprovementsin Cash-Registers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make the different views.

Figure 1 is a rear elevation, partly in sec tion, of a registering apparatus embodying the features of my improvement. Fig. 2 is a vertical transverse section,taken on the line .00 act Fig. 1. Fig. 3 represents a section taken from the front of the apparatus, for the purpose of giving a more complete viewof the dial. Fig. 4. is a section of one of the parts. Fig. 5 is a view of the same as seen from a different direction. Fig. 6 is a sectional view of one of the parts. Fig. 7 is a sectional view of connecting parts. Fig. Sis asectional View more fully illustrating the construction and relation of the parts.

A AA is an inclosing-case, to bemade pref erably of metal, with the parts shownintegral with each other.

B is a ratchet-wheel having a sleeve or hub, b, integral therewith, by means of which it is loosely secured upon and supported by a shaft, B, having bearings in the front of the inclosing-case A, and the framepiece G, secured thereto by any suitable means.

D is aratchet-wheel of less diameter than the wheel B, and rigidly secured to the shaft B, which is provided at its rear end with a pinion, B", having five cogs, for a purpose hereinafter set forth. The shaft B and the sleeve or huh I) of the ratchet-wheel B pass through the front of the casing A, which is provided with a registering-dial, A, inclosed by the circular part of the case, and havingavisionglass, a. The shaft B is provided at its front end with an indicator, a, and the front end of the sleeve or hub b is provided with an indicator, a of greater length than the indicator a.

E is a gear-wheel havingfifty cogs meshing with the pinion B and mounted on a shalt, F, having bearings in the frame-piece C, and reg istering dial-plate G, having integral therewith curvcd extensions G G, by means of which it is secured to the inclosing-case, as fully shown in Fig. 1.

H is a bell suitably secured to the inclosingcase, to which is also secured, by means of a -pivot, i, a hammer, I, in a position to engage with the bell H, the ratchet-wheel B, and a tension-spring, J.

B is a pawl afiixed to the side of the ratclr et-wheel B. The pawl B has an extension, B, which occupies the position of a serration of the ratchet-wheel, which is deprived of a serration in order to make room for said pawlextension B. 1

K is a rod provided with a knob, K, a collar, 7t, and aspiral-spring, 7.1", which supports the roll K by pressure against the collar 1; and eye 7;.

Pivoted to the lower end of the rod K is a pawl, K, having a weighted extension, K, and arranged to engage with the ratchct-wheel B. The pawl B is arranged to engage with the ratchet-wheel D once only to each revolution of the ratchet-wheel B, as will be here inafter more fully explained, during the revolution of which wheel the pawl is held clear of the serrations of the wheel D by means of the spring 2), as shown in Figs. 1, (3, and 8.

L L and L L are rubbers or brakes arranged to bear upon the ratchet-wheels B and D and prevent them from moving more than one serration at a time.

The mechanism is operated by means of the pawl K K, through pressure on the rod K, which, because of the knob K, can move only for enough to turn the wheel B the distance of one serration, after which the spiral spring 76 will raise the rod to the position shown.

Vith each payment received the employe is required to press down the rod K and move the ratchet-wheel B one serration, which will allow the inner end of the hammer I to drop over the point of the serration, when the spring J will force the outer end against the bell H and cause it to ring. Failure of the employe to register each payment by said ringing is to be considered as evidence of fraud. \Vith each revolution of the wheel B the pawl K will come in contact with the extension B of the pawl 13 and cause the said pawl to engage with and move the ratchetwheel D the distance of one serration, the shaft of which is provided with a pinion, 13 which engages with and moves the cog-wheel E, to the outer end of which is affixed an indicator, M, and a dial or index register, G. Because of the ratchet-wheel 13 having one hundred serrations, each revolution made by it will register one hundred receipts. As there are one hundred serrations in the ratchet-wheel D, and as it moves but one serration to each revolution of the wheel 13, it will require one hundred revolutions of the latter to produce one revolution of the wheel D, which for that reason will register one thousand payments. As the five-cog pinion 13 which engages with the gear-wheel E, having fifty cogs, is secured to the same shaft as the ratchet-wheel D, it will take ten revolutions of the latter to pro duee one revolution of the wheel E, and each single revolution of the wheel D and pinion B will move the indicator ll'l one space or, number on the indexregister G, or a proportional distance of the space between the num bers thereon, according to the circumstances.

The apparatus should be started with both the indicatorl1ands a a at zero, and when the long hand makes one revolution the short hand will move up one space, and so on throughout.

The rear of the apparatus is to be closed, and the dial G is not to be accessible, except to the employer, who, by examining the rear dial, can ascertain at any time the exaetnumber of receipts registered, and may call for an account corresponding thereto.

Any suitable door and lock maybe used for securing the inclosure of the dial G.

Having explained the construction and operation of my improvement, what I claim as new, and desire to secure by Letters Patent, 1s

The ratchet -wlieels B D, in combination with the pawl mechanism K K K" K, and the pawl mech anism 13913, secured to the wheel 13, sleeve 1), dial A, indicators a a shaft B, pinion B shaft F, gear-wheel E, mounted on shaft F, the dial G, and indicator lll, all co11- structed and arranged to operate substantially as specified, for the purpose set forth.

In testimony that I claim the foregoing as my own I aflix my signature in presence of two witnesses.

THOMAS lilUNNELL.
